Question

Mr. H, the physics teacher, walked 3 m from the classroom door, made a right turn and walked 4 m towards the back of the classroom. What is Mr. H’s displacement from the classroom door?

Answer 1

Mr. H's displacement from the classroom door is 7 m.

Step-by-step explanation:

The displacement of Mr. H from the classroom door can be calculated by finding the difference between his final position and his initial position. In this case, his initial position is at the classroom door, which is considered the reference point. Given that he walked 3 m from the classroom door and then made a right turn and walked 4 m towards the back of the classroom, his final position can be calculated as follows:

xf = 3 m + 4 m = 7 m

Therefore, Mr. H's displacement from the classroom door is 7 m.
